摘　　要：以2011年9-11月和2012年3-5月在舟山渔场捕获的496尾龙头鱼为样本,采用主成分分析、回归分析等方法对龙头鱼矢耳石形态特征进行了研究。结果显示,龙头鱼矢耳石呈不规则卵圆形,其基叶较长,翼叶不发达;后端具波纹状叶形晶状突,无后基叶和侧基叶。龙头鱼矢耳石形态指标AD(L)、CE(H)、OA(L1)、OD(L3)、AH(b1)、BG(b2)、AB(c1)和AG(c2)可代表龙头鱼矢耳石主要形态特征。8个指标均与体长及纯重呈显著正相关,其中L与体长及纯重相关性最强。龙头鱼矢耳石各指标值对长轴长的比值与其体长均不存在显著相关性,其耳石形态在生长过程中较为稳定。Based on 496 specimens of Harpodon nehereus collected from Zhoushan Fishery in China in September to November, 2011 and March to May, 2012, morphological characters of the right otoliths were measured and analyzed by principal component analysis, regression analysis, etc. The results showed that the otoliths were irregular oval; the rostrum of otoliths was long and the anti-rostrum was underdeveloped; the end of otoliths had ripple leafed aragonite crystal without postrostrum and pararostrum. The morphological parameters（L, H, L1, L3, b2, c1, c2） could represent the most of H. nehereus′ otolith morphology. They and body length（or net weight） were positive correlation and the correlation of L and body length（or net weight） were the most strong. The ratios of the otolith parameters to the long axial length were no obviously correlate with body length. Otolith morphology of H. nehereus was stable during growth and development.
